Answer 3

Calculating the Circumference of a Circle

To find the circumference of a circle, you can use the formula:

Circumference (C) = 2 * π * radius

Given that the radius is 2 dm, we can substitute this value into the formula to find the circumference.

C = 2 * π * 2

Now, let's calculate the circumference using the value of π as approximately 3.14.

C = 2 * 3.14 * 2

C = 12.56 dm

So, the circumference of the circle with a radius of 2 dm is 12.56 dm.
